FASTENING nEvrcE.

To all 'whom 'it may concern: l

Be it known that I, FREDERICK D. SCHNEI- DEE, a citizen of the UnitedStates, resident of Bedford, county -of Cuyahoga, and State of Ohio,have invented a new and useful Improvement in Fastening Devices, ofwhich the following is a specification, the principle of the inventionbeing herein explained and the best mode in which I have contemplateol4applying that principle, so as to distinguish it from other inventions.

My invention relates to a fasteningdef vice, and more particularly toone adapted 'esecially'for use in the fastening of members irectly"exposed to inclement weather, im-

-plying moisture. Heretofore devices adapted; to serve the same generalpurposes have been rather inefficient in the way of an absoluteprevention of leakage at the connections.

Accordingly, the Iobject of my invention.

is the provision ofl a device which, while fulfilling all the ordinarydemands for simplicity and effectiveness, will nevertheless positivelypreclude the possibility of any save a water-tight fit, at all times.

The said invention consists of means hereinafter fully described andparticularly set forth in the claims.

The annexed drawing and the following description set forth in detailcertain means embodying my invention, the disclosed means, however,constituting but one of various mechanical forms in which the principleof the invention may be used.

In said annexed drawing Figure l is an enlarged vertical cross-sectionof the simplest and4 preferred form of my device.

Fig. 2 is a vertical cross-section, actual size,

showing a specific application. Fig. 3 is an enlarged verticalcross-section ofv a modifi-- cation.

Like letters and figures designate likeparts throughout the severalviews My invention consists of a clench memberl and washer incombination. 'Its function is a conjunctlve use with any member 1t mayAbe desired to fasten, and which is in the drawing, by way of example,shown to be a cross sectionof a single arch of corrugated rooing. Withmore 'particular reference thereto, the roof A is provided with anopenin a through which it is to be fastened to tie underlying purlinsD.' rlhis is Specification of Letters Patent.

`now generally accomplished by twisting the ends of two adjacent nailsin the same corrugation around each other on the under side of vthepurlin.

To best effect the particular purpose of my invention, I provide adownwardly tapered washer B, the smaller end b being necessarily` ofsuch a' size that it may be readily inserted into the opening a',whereas thelarger end is in turn of a size incapable ofpassing'therethrough. The upper side of the washer 1s more abruptlysloped or cut away, so as to present a thin rim b2 contiguous to theopening therein. A nail C having a head c extends through both washerand opening in the customary manner, and is adapted, while being securedto the pur-lin in any approved manner, todraw thewasher into theopening,thus tightlyl wedging it therein. 'As will now be apparent, there isafforded in consequence avery sharp surface ofl contact for the head ofthe nail. In practice, a jamming of the metal is caused at this upperrim so formed, and hence aifords absolutely no -likelihood of a loose orexposed jointv between the nail and washer. In the modification shown inFig. 3, the upper side of the washer is concave,

to form a similar rim, save that in lthis case it is outwardly disposed,that is non'contig- .nous to the opening. It is best to associate withthis modified form of washer a nail or other equivalent member having acapped head c2, as shown. This should be of such a size that it willcompletely cover the upper or larger end of the washer, and in this way,due to the jamming of the head on. the

rim, will, likewise exclude whatever rainA sloping away fromits openingto form a with a tapered washer having its upper face I sharp rim; of amember, provided With a head, projecting through the opening in thewasher und aduptedto engage sind run.

As a new artzlcle of manufacture, a fas- `telling device comprising the'combination with a downwardly tapered Washer having its upper facesloping downwardly from, A to form a sharp rim contiguous to, its open-`ing;4 of a nail projecting through the opening and adapted to engagesaid rim.
